Transition level penalty

<< < (2/3) > >>

EHM-2089 Vincent:
Cool, good info about the TL Penalty. I almost everytime when I flew, every since I got the penalty make it a habit not to cross FL17000 unless required ;D and if yes then ensure that i keep pressing the letter B so that its automatically set to the right setting.

I guess to make things a little more real, its good to have a flight chart done / flight log printed from the FS 2004 NavLog option itself. And then monitor the flight plan regularly. At the altitude of FL180, press B and you can avoid the penalty, thats my common modus operandi!!.

EHM-0948 Bruno:
.. or, you can do like me that sets the AutoPilot for 17900ft :) .. before climbing to final flight level ;D

EHM-2089 Vincent:
Yeah, I agree on that Bruno... I want to keep safe of air currents, lest the plane tries to do some acrobatics and shooting over 18000 and then lowering etc... so I keep safe af FL170 and then the letter B is my friend. He is pressed constantly - sorry hammered constantly!!! :P

EHM-1798 Conrad:
I would try to avoid "b" at stages, because it can sometimes be innacurate. For example, London Control instructs you to climb to FL130, if you are still at the local QNH of which you went through the transition layer with. Then your altitude will be wrong. You should allways change it when passing the real TL to qnh 1013 - or mercury 29.92.

For example..

Climbing out of heathrow, TA = 6000ft, TL= 060 - So you should set the Standard qnh when passing.

EHM-0654 Murray:
Conrad, you (should) know as well as I that introducing TL into this discussion is like throwing a live grenade into a kiddies play area - at some point, there will be an accident... ;D

(And by way of explanation from those that don't know) Unlike TA [Transition Altitude] which is fixed by each civil authority (CAA in the UK) for each field/area, the TL [Transition Level] varies depending on the pressure at ground level and the TA for the field in question.

So, as Conners rightly points out, the TA at EGLL is 6000ft, but the TL will be one of FL55 thru FL80 (in increments of 500ft), depending on the QNH at the time of descent.
